My answer has been that it isn't quick, and may take many years. How can you turn around the traditional teaching and learning paradigm - one that has been operating largely unchanged for many, many decades - in a year or two?
Of course, my answer is both correct and incorrect.
Organization wide change
I keep thinking in terms of whole organization change, where organization wide academic change leads to organization wide academic improvement. This is slow, as it involves many people and the modification of many different thought processes in many individual minds.
Individual teacher/class change
However, it is much quicker ( and much, much easier) for academic lift to occur in a class or two, taught by a switched on and energized teacher. This is the sort of thing that gets media attention as it can happen in a semester. However, it is a spot fire when what is really needed is to set the whole forest alight. It doesn't change the whole organization.
And if we don't provide increased academic opportunities for all students, we are wasting the potential of the huge advantages available to students from technology enhanced learning and teaching.
